State-of-the-art spatially resolved Raman spectroscopy so far has had to rely on the
time-consuming technique of sequential scanning of the sample under study. However,
advanced instrumentation for modern astronomical telescopes has spawned the development of the powerful technique of Integral Field Spectroscopy that enables to collect simultaneously... von Leibniz-Institut für Astrophysik, innoFSPEC Potsdammehr

Is that powder in the envelope dangerous? Is the right mixture flowing through the pipe? Is the semiconductor doped correctly? Terahertz spectroscopy can help answer these and other critical questions. This article first describes some of the special features of terahertz spectroscopy in relation to substances in their various physical states,... von Joachim Jonuscheit, D. Molter, F. Ellrich, R.

Gratings with periods smaller than visible wavelengths exhibit colourising effects in the zeroth diffraction order when its profile is designed so that electromagnetic resonances are excited on the grating. These resonances have a spectral selective influence to the light spectrum and allow colour filtering of even unpolarised white light. Apart... von Hans Lochbihler, Papierfabrik Louisenthal GmbH, Gmund, Germanymehr
